<p>A biological replacement ligament is provided which includes a compressible core (12) and a separate flexible outer sheath (14) having a first end (22), a second end (24), and a generally tubular intermediate portion (26). The intermediate portion surrounds the compressible core, whereby the application of tension between the first and second ends causes the intermediate portion to constrict upon the compressible core thereby allowing elongation of the ligament to modulate the tension between the first and second ends. The amount of elongation and tension modulation is primarily determined by the compressibility of the core . <IMAGE></p> |
